I haven't installed my Weber yet so I can't give you any details, but everyone I've asked in real life swears by Webers. They supposedly improve horsepower and torque, provide smoother idle, and perform better during cold starts and warm starts than stock. I've heard from a few people that they even improve highway mileage!

City Hunter used to run a Weber on his Colt, I'm sure he can give you some details.

From what I understand, webers are better performers but need constant adjustments. Mikuni carbs supposedly stay tuned for very long periods and don't require frequent adjustment. Basically, Weber for performance, Mikuni for reliability(only if they are the Japanese ones, not the Italian ones)

For a set it and leave it...you CANNOT beat Mikuni PHH..they are less fussy to changes in temperature, humidity, altitude AND atmospheric changes in weather. A great carb for the street (or track)...my personal favorite.

Webers are VERY fussy if you set them in the morning and it is dry and sunny, then if it rains at night and is damp, you will find yourself re-jetting them or out with your sync tool checking them...a pain in the butt.

OE \ SK (or Sanyo Kiki) are similar to the Dellortos and I had excellent experience with them, they behave more like the PHH Mikuni...so yes I love them.

BTW for ultimate power when it is dry and sunny and very low humidity...Webers rule on the track.
